Thanks Andrew, I put the steps and log files here:
http://www.bootchart.org/misc/ecj/ecj-native.html
It seems that ecj was actually running native in both cases (with or
without gnu.gcj.precompiled.db.path). Which, looking at the source code
for com.sun.tools.javac.Main, seems right:
@71
loader = new URLClassLoader(new URL[] {
new URL("gcjlib://" + Config.ECJLIB_INST_DIR + "/" + libname)});
(libname being "lib-org-eclipse-jdt.so")
Moving lib-org-eclipse-jdt.so out of the way speeds up gij/ecj
considerably.
Shouldn't precompiled libraries be configured in runtime, as opposed to
in Main.java? And I'm not sure why it's actually faster when running
interpreted.
